Frequently Asked Questions

What are hreflang tags and when should I use them?

Hreflang tags are HTML attributes that tell search engines which language and regional version of a page to serve to users in different locations. You should use them when your website has content in multiple languages or when you have region-specific versions of the same content, such as separate pages for US English and UK English audiences.

What happens if hreflang tags are misconfigured?

Misconfigured hreflang tags can cause search engines to show the wrong language version to users, leading to poor user experience and higher bounce rates. Common errors include missing return tags, incorrect language codes, and self-referencing omissions. These mistakes can result in duplicate content issues and diluted rankings across your international pages.

Do I need an x-default hreflang tag?

Yes, including an x-default hreflang tag is strongly recommended. It tells search engines which page to show when no other language or region matches the user's location, typically pointing to your main international page or a language selector page. Without x-default, search engines must guess which version to display, which may not be the best choice for your visitors.
